Systems and methods for improved post-resuscitation recovery

Abstract

A method for performing cardiopulmonary resuscitation (CPR) includes elevating the head, heart and shoulders of an individual from a starting elevation angle to a final elevation angle greater than zero degrees relative to horizontal while performing CPR by repeatedly compressing the chest. The method includes elevating the brain within a time period selected to be slow enough to permit a sufficient amount of blood to flow to the brain throughout the elevation time period. The method also includes regulating the intrathoracic pressure of the individual while performing CPR. The performance of chest compressions is stopped and after stopping the performance of chest compressions, the head, heart, and shoulders are promptly from the final elevation angle within a timeframe selected to prevent significant drainage of blood from the brain until the head, heart and shoulders are lowered.

AI Technical Summary

Benefits of technology

The invention is about a new way of giving CPR to a patient who is in a head and thorax up position. This position helps to increase the pressure in the brain and decrease pressure in the heart, which can help save the patient's life. The method involves raising the patient's head and heart and compressing the chest repeatedly. The pressure in the patient's body is regulated, and when the compressions stop, the patient's head and heart are quickly lowered to prevent brain damage. Overall, this new technique provides a safer and more effective way to perform CPR for longer periods of time.

Problems solved by technology

Such techniques result in lower right-atrial pressures and intracranial pressure while increasing cerebral perfusion pressure, cerebral output, and systolic blood pressure (SBP) compared with CPR administered to an individual in the supine position.
